elcYcLE-f-H/'rlvnl ril SPECIFICATION forming part of Letters Patent No. 608,566, dated August 9, 1898. `Application filed December 23, 1896;; Serial No. 616,751. NO lllOtlPl.)v

To all whom it may concern:

Be it known that I, EDWARD ANDERSON, a citizen of the United States, residing at Elgin, in the county of Kane and State of Illinois, have invented a new and useful Bicycle-Handle, of which the following is a speciiication.

This invention relates to handle-bars for bicycles, velocipedes, and vehicles that are steered'by means of abar provided with grips; and the object of the improvement is to provide simple and effective means for admitting of thehandle-bar being adjusted to any position within certain limits to suit the ease and comfort of the rider or the person guiding the machine or vehicle. v Y

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.V y

The improvement is susceptible of various changes in the form, proportion,and the minor details of construction without departingfrorn the principle or sacrificing any ofthe advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which- Figure lis a front view of a vhandlebar having the invention applied thereto. Fig. 2 is a side elevation thereof. Fig. 3 is a detail view of the head-lug, showing the middle portion of the handle-bar and the clampscrew. Fig. 4 is av detail view of the locknut and guide. thumb or clamp nut. Fig. 6 is a detail section showing the parts assembled and in such relation as to admit of .the handle-bar being moved to any required position.

Corresponding and like parts are referred:V

to in the following description and indicated in the several views of the drawings by the same reference characters. i

The handle-bar 1, head 2, and head-lug 3 may be'bf any desired' pattern, and the handle-bar is rotatably mounted within the headlug, so as to be turned to any position to suit the convenience of the user. The head-lug has a transverse slot 4 and toothed flanges 5, bordering upon the sides of thesaid slot, the teeth of the flanges corresponding and alining longitudinally of the handle bar. A clamp-screw 6 is secured at its inner end to Fig. 5 is a detail view of the` l the handle-bar and operates inthe slot 4, and

the means for securing thehandle-bar in the located position are mounted thereon 'and consist of a lock-nut '7 and a thumb or clamp nut 8.

The lock-nut 7 has oppositely-disposed cogs E) at its inner end to engage with the toothed iianges 5 and secure the handle-bar when moved to the required position. The outer end of the bore or opening of the lock-nut is enlarged and internally threaded to receive the externally-threaded projection 10 of the thu-mb or clamp nut S, and this lock-nut is loosely mounted upon the clamp-screw, so as to move thereon without interference from its thread. The lock-nut is provided with a guide for holding its cogs 9 in proper position for engaging the teeth of the fianges when the parts are out of engagement, and this guide consists of a tongue 1l, detachably secured to the lock-nut, at one side thereof, and projecting into the space between the iianges 5. The tongue, whichlis of sufficient length to engage the flanges when the 'cogs are out of engagement with the same, is adapted to operate at either side of the screw, whereby the lock-nut may be readily reversed to bring the tongue in advance or in rear of the screw, so that the latter may be arranged at the eX- treme ends of theslot. Should the tongue become broken, it may be readily replaced.

The thumb or clamp nut S has screwthread connection vwith the clamp-screw 6, and is formed with a tubular projection 10 on its inner side, which is externally threaded to match with the internally-threaded portion of the lock-nut. The clamp-screw is formed with a right thread and the projection lO with a left thread,'or the relation of the threads may be reversed without affecting the operation of theinventiom so long as one thread is right and the other left. A slight movement of the thumb or clamp nut is increased in effect upon the lock-nut by reason of the opposite disposition of the threads, as is obvious. Upon turning the thumb or clamp nut to the right it will move inward uponthe 'clampscrew and carry the lock-nut Vwith it; and atv the same time the lock-nut will have an independent movement inward by reason of its screw-thread connection with the thumb-nut, because the tendency is to separate the lock IOO and thumb nuts upon turning the latter to the right. By reason of the inverse screwthread connection of the thumb or clamp nut with the clamp-screw and lock-nut the latter is moved rapidly into and out of engagement with the toothed fianges, and it the pitch of the right and lett threads is the same the movement of the lock-nut is double that of the thumb or clamp nut, as will be readily understood.

To adjust the handle-bar the thumb or clamp nut is moved in the proper direction so as to disengage the lock-nut from the toothed flanges, thereby liberating the handle-bar, so it can be turned to the required position, and upon retightening the thumbnut the handle-bar has its position fixed.

rl`he head-lug may be supplied with flanges 5 upon opposite sides, as shown in Fig. t), thereby making provision for reversing the handle-bar, as willbe readily understood. In

this connection it will be observed that the slot t must be extended to admit of the clamp-screw G having its position reversed.

Having thus described the invention, what is elaimed as new is- In a device of the class described, the Combination of a headed lug having a slot and provided with toothed ilanges located at opposite sides of the slot, ahandle-bar mounted to turn in said lug, a screw connected with the handle-bar and passing through the slot, aloek-nut slidably mountedupon the elamping-screw and having oppositely-disposed eogs to interlock with the toothed flanges, a tongue detaehably mounted on the lock-nut at one side thereof and arranged in the spaee between the [langes to form a guide, said tongue being adapted to operate in advance or in rear of the screw, whereby the lock-nut may be reversed to permit the screw to be arranged at the extreme ends et the slot, and a clamping-nut engaging the screw and having a threaded connection with the leek-nut, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afxed my signature in the presence of two witnesses.
